" Wait, this reminds me of..."rReferentiality is always fun. Here's some albums that have references to artists, novelists, poets,or philosophers. I'm sure there are tons of others but here are some according to my preferences. Feel free to add yours!

Their love for poetry and stuff is clear. Not to mention the several references to the Byronic Hero and the figure of Lucifer as revolutionary, they dressed Poe's "Alone" with the most proper music it could be done.(For those who have the physical copy, search a little and you may find some Sade lines)

Everything here has to do with alchemy and mysticism stuff. But notable are the several William Blake references( album cover, Urizen, etc). Bruce has done a great job with this one as far as the lyrics are concerned.

This one is a treasure. The whole album displays many of Lautremont's lines form The Chants of Maldoror, which is easily the most metal and prodigious piece I've read. You can also find Nietzsche , Baudelaire , and Trakl here.
